AUXILIARY SPRING FOR AUTOMOBILES.

Specification of Letters Patent.

Patented Dec. 22, 1908.

Application filed January 20, 1908. Serial 1V0. 411.764.

T 0 all whom it may concern:

Be it known that I, LAWRENCE D. COL- LINs, a citizen of the United States, residing at Pasadena, in the county of Los Angeles and State of California, have invented new and useful Auxiliary Springs for Automo-.

biles, of which the following is a specifica- This invention relates to auxiliary springs construction and combination hereinafter described.

The accompanying drawings illustrate the invention, and referring thereto, Figure 1 is a side elevation of one form of auxiliary springs showing them applied to an automobile frame having a hook shaped end. Fig. 2 is a similar view showing a slightly moditied form. Fig- 3 is a similar view showing the form shown in Fig. 1 as applied to a frame having a bowed end. Fig. 4 is an enlarged section on line v -r Fig. 1. Fig. is

a perspective view'of one member or the divided top plate. Fig. 6 is aperspeclive view of the other member of the divided top )late. Fig. 7 is a perspective view of the ottom plate.

In the form shown in Fig. 1, 1 designates the hook shaped rear end of an automobile frame and 2 designates one of the regular rear springs thereof. A bolt 3 passes through the eye of the frame member 1, the bolt projecting each side of the eye and pivoted to the bolt 3 is a divided top plate com prising members 4 and 5 shown respectively in detail in Figs. 5 and 6. The member 4 is provided with a perforated lug 6 and with two horizontal perforated. wings 7, while the member 5 is provided with a vertical perforated lug 8 and its lower portion 9 is pro Vided witlrperforations in each end, which perforations register with the perforations in the wings 7 of the member 4, the wings 7 lapping over the lower portion 9 and the two members being fastened together by bolts 10 which pass through the perforations. The wings 6 and 8 are pivoted to the bolt 3.

11 designates the bottom plate having perforated end wings 12 and perforated side Wings 13. Short bolts 14 are attached to the perforated wings 12 and form studs for re taining in position the lower ends of a pair of coil compression springs 15, the upper ends of said springs being retained in position by the bolts 10.

l 1 i l i I I i Passing through the perforated sidewings 13 is a pair of vertical links 1.6, the upper portion of each link being flattened and having a slot 17 which slides over the'outer end of the bolt 3, the upper end of each link 16 being pivoted to a pin 18 in the rear end of the regular spring 2. Arranged in the center of the bottom plate 11 is a stud 19 to which is secured the lower end of a buffer sprin 20, the upper end of spring 20 lying somewhat below the divided top plate.-

In operation the links 16 are suspended from the regular springs 2 and as the automobile frame moves down it carries down the divided top plate thus compressing springs 15 somewhat and thereby softening the shock on the regular spring 2. After the divii'led top plate has moved down a certain distance and emnpressed the springs 15 it strikes the. buffer spring 20 and the latter still further cushions the downward movement so that the regular spring 2 is relieved of sharp jolts and the spring action considered as a whole is rendered verysmooth and even.

T he form shown in Fig. 1 may also be applied to automobiles wherein the frame member 1 is bowed instead of being hook shaped as shown in Fig 3, in which latter case a stud 21 projects laterally outside of the frame member 1 and the divided top plate is pivoted to stud 21 instead of the wings 6 and 8 straddling the eye as shown in Fig. 1.

Fig. 2 shows a slight modification in which each member 4 and 5 of the divided to plate has a laterally perforatedlug 22 t ouglr which the link 16 slides, the latter being a round rod from end to end pivoted at the top to the upper leaf of the spring 2.

The form shown in. Fig. 2 is adapted for use only on the hook shaped frame member as shown, while the form shown in Fig. 1 may be applied either to the hook shaped frame member 1 or to the bowed frame member 1 as shown in Fig. 3.

\Vhat I claim is: i

1. Auxiliary springs for automobiles comprising a divided top plate formed of two members each having a perforated ear, a pivot passing through the ears and through the frame of the automobile, a bottom plate, links pivoted to the regular springs of the automobile and supporting the bottom plate, said links being slidable past the divided top tom plate with its upper end terminating short of the divided top plate.

3. Auxiliary springs for automobiles comprising a divided top plate consisting of two members each having perforated horizontal wings bolted together and each having perforated vertical wings, a bolt through the eye of the frame member of the automobile to which said vertical wings are pivoted,

links connected to the regular springs of the automobile and slidably extending past the divided top slate, a bottom plate having two 1pplrforated side wings through which said ks extend, nuts on the lower ends of the links supporting the bottom plate, and coil compression springs interposed between the bottom plate and the divided top plate.

4. Auxiliary springs for automobiles comprising a divided top plate consisting of two members each having perforated horizontal wings bolted together and each having perforated vertical wings, a bolt through the eye of the frame member of the automobile to which said vertical wings are pivoted, links connected to the regular springs of the automobile and slidably extending past the divided top plate, a bottom plate having two perforated side wings through which said links rising a divided top'plate pivoted to the extend, nuts onthe lower ends of the links eye of the frame member of the automobile to which said vertical wings are pivoted, links connected to the regular springs of the automobile and slidably extending past the divided top plate, a bottom plate having two perforated side wings through which said links extend, nuts on the lower endsof the links supporting the bottom plate,'coil compression springs interposed between the bottom plate and the divided top plate, the upperends of said springs being held in position by the bolts which unite the two members of the to plate, belts in the bottom plate holding t e lower ends of said springs in position, a bolt in the center of said bottom plate, and a buffer spring attached to the latter bolt, the upper end of the bufl'er spring terminating short of the divided top. p ate.

In testimony whereof, I have hereunto set my hand at Los Angeles, California, this 11th (lay of January, 1908.
